mysql --prompt

 mysql --prompt修改命令行链接mysql时的提示符,shell脚本示例如下

#!/bin/bash

case $1 in
    crm) cmd='mysql  -h192.168.1.2 -uroot -proot -P3306 -Dcrm'
;;
*)
    echo "数据库变量不存在:$1 仅支持输入 crm"
    exit 0
;;
esac
shift 1
$cmd --prompt="[\u@\h:\p(\d) \R:\m:\s] mysql>" --default-character-set=utf8 -A "$@"

在命令行输入 db crm 执行效果如下

liuzhao ~ $ db crm
